HI I'M NEW TO C# I'M CREATING MENU
AND DONE BUT THE PROBLEM IS WHEN I CLICK THE MENU ITEM 3 TIMES THE FORM WILL SHOW 3 TIMES AND I WANT TRAP THAT IF THE FORM ALREADY LOADED YOU CANT OPEN THE FORM TWICE UNLESS THE USER CLOSE THE FORM..
HOW TO TRAP FORM TO LOAD ONLY ONCE
|
|
|
|
|
If you use ShowDialog() instead Show(). If you use ShowModal(), you will prevent code execution till you close your form.
OR declare Form with a global or class scope. And you can put boolean value inside form. And use OnLoad event and Close event to set it to true or false. And before showing you should check that boolean.
PS: It is rude to shout

can you give me sample sir on how to do it...
|
|
|
|

First way:
Form form1 = new Form();
form1.ShowDiealog();
second way:
public class testForm : Form
{
...
public bool opend;
private void testForm_OnLoad(Object sender, EventArgs e)
{
opend = true;
}
private void testForm_OnClosing(Object sender, EventArgs e)
{
opend = false;
}
...
}
testForm form1 = new testForm(1);
if (!form1.opend)
form1.Show();
else
form1.Focus();

and what is your question? What have you done so far?
|
|
|
|
|
when user Insert New Record textbox generate auto number, like 1,2,3
|
|
|
|
|
To increase number, look at this code:
textbox1.Text = (Convert.ToInt32(textbox1.Text)+1).ToString();
|
|
|
|
|
|
You can look at Int32.TryParse. To convert to int. The difference between .TryParse() and Convert is that Convert will throw you an exception if it cannot convert. Forgot witch one it is. TryParse will return false if faild. My preferences is Convert method

Insert a record where? Because if the answer is a database then the database should be generating the number - not your application.

How to make setup of window application in .net of 10 days block. Means software will work for 10 days only.
|
|
|
|
|
There are many ways of doing this. The easiest (though least secure) way of doing this is to store the date it was installed into a text file and then check that file each time the application loads. If 10 days have elapsed, then exit.
|
|
|
|
|
But if user has changed the system date then it will not work
|
|
|
|
|
people can delete the txt file also right? Then the application can continue work?

Hi. We're having a little problem in allowing the user click/press any button from a group of buttons inside a panel. What we want is after clicking/pressing one button that is not one of the group of buttons, the user will be allowed to click/press any of the buttons in the panel. All the buttons inside the panel represent the alphabet that's why we want to do that. The button that will be clicked before doing that is a start button. So can anyone help us?
|
|
|
|
|
So you start off with the buttons enabled property as False then when the start button is clicked you go through each control in Panel.Controls and if it is a button and not the start button set the enabled property to True.
You may want to put the alphabet buttons in a groupbox to further segregate them from any other controls, in this case you go through the GroupBox.Controls collection instead.

I am counting words in string, that i get from text file. Using this code i get always 1 more word in counting. What could be wrong?
int stevec = 0;
string s="avc sde s a s"
string[] words = Regex.Split(s, @"[\S]+");
foreach (string word in words)
{
stevec++;
}
After deb stevec has value 6. But there are only 5 words.

I tested your regex.. Making the S lowercase did the trick.

gee. Did you consider looking what is inside the words array? to fix a faulty program, you need to open your eyes and look around. Nobody is going to do that for you.
If you get all the facts, and still can't figure it out, then post a real question, clear and well documented.

|
|
Sorry.. while i was debuggin i couldn't see words with breakpoints, even in console they weren't visible. And with greater S using only Regex.Match the counting was correct, thats why i asked here. Anyway, thanks for help.

there are many debugging tools, the simplest one is Console.WriteLine; it works always, never had a problem with it.
